Positive, negative, and zero gradients are important for understanding line graphs and how they work.
Positive Gradient: A positive gradient means the line goes up from left to right. This shows that when the x-values go up, the y-values also go up. For example, if we look at the line for the equation (y = 2x), it will rise as the x-value increases.
Negative Gradient: A negative gradient means the line goes down from left to right. This means that as the x-values go up, the y-values go down. For instance, if we have the equation (y = -3x + 5), the line will drop as you move to the right.
Zero Gradient: A zero gradient means the line is flat, or horizontal. This shows that the y-value stays the same no matter how the x-value changes. An example of this is (y = 4), which is a straight line at (y=4).
Knowing about these gradients helps us understand trends in data better!
